VERSION

Version 0.06

SYNOPSIS

  use Geo::Coder::US::Census;

  my $geo_coder = Geo::Coder::US::Census->new();
  my $location = $geo_coder->geocode(location => '4600 Silver Hill Rd., Suitland, MD');
  # Sometimes the server gives a 500 error on this
  $location = $geo_coder->geocode(location => '4600 Silver Hill Rd., Suitland, MD, USA');

DESCRIPTION

Geo::Coder::US::Census provides an interface to geocoding.geo.census.gov. Geo::Coder::US no longer seems to work.

METHODS

new

$geo_coder = Geo::Coder::US::Census->new();
my $ua = LWP::UserAgent->new();
$ua->env_proxy(1);
$geo_coder = Geo::Coder::US::Census->new(ua => $ua);

geocode

$location = $geo_coder->geocode(location => $location);
# @location = $geo_coder->geocode(location => $location);

print 'Latitude: ', $location->{'latt'}, "\n";
print 'Longitude: ', $location->{'longt'}, "\n";

ua

Accessor method to get and set UserAgent object used internally. You can call env_proxy for example, to get the proxy information from environment variables:

$geo_coder->ua()->env_proxy(1);

You can also set your own User-Agent object:

$geo_coder->ua(LWP::UserAgent::Throttled->new());

reverse_geocode

# $location = $geo_coder->reverse_geocode(latlng => '37.778907,-122.39732');

# Similar to geocode except it expects a latitude/longitude parameter.

Not supported.

run

You can also run this module from the command line:

perl Census.pm 1600 Pennsylvania Avenue NW, Washington DC
